RIM FDR AUTOMOBILE-TIRES.

Specification of Letters Patent.

PatentedFeb. 14, 191 n Application filed January 25, i910. Serial No.539,949.-

T 0 all whom it may concern:

Be it known that I, Gusravn H. Boonn- IIAGEN, a citizen of the UnitedStates. residing at Beemer, in the county of Gaming and State ofNebraska, have invented certain new and useful Improvements in Rims forAutomobile-Tires; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to new and useful improvements in means forattaching tires to vehicles and adapted more particularly to be used forsecuring automobile tires in position on the wheels, and my object is toprovide a removable ring for the .wheel, whereby the tire and its casingmay be quickly removed from or placed in positionon the wheel;

A. further object is to so construct. the rim that the inflation of thetire will interlock parts of the rim.

A further object is to provide a locking ring which is'adapted to holdthe parts of the rim in locked position.

Other objects and a .lvantages will be hereinafter referred to and moreparticularly pointed out in the specification and claims. y

In the accompanying drawings which are made a part of this application,Figure 1 is a side elevation of the rim in its locked posi tion. Fig. 2is a similar view of the locking portion of the rim. Fig. 3 is anelevation of the rim with the locking mechanism removed. Fig. i is anelevation of the movable portion of the rim. Fig. 5 is a' transversesectional view on an enlarged scale through the rim. Fig. 6 is a detailsectional view of a portion of the movable section of the rim, and, Fig.7 is a similar view of the stationary portion of the rim. Fig. 8 is asegmental perspective view of the locking ring about to be applied tothe body of the rim.

Referring to the drawings in which simi- -lar reference numeralsdesignate correspending parts throughout the several views, 1 indicatesthe body portionof the rim proper, which portion is in the form of aband andis preferably fixed to the folly of the wheel, said body portionhaving an up wardly curved flange 2 at one edge, the- .inner face ofwhich. is provided with a groove 3, which groove is preferablysubstantially U shaped and adapted to receive the usual form of bead ofthe tire (not shown) g Adapted to fitaround the outer face of the body 1and move t-hereover is a ring 4, the inner face of which is alsoprovided with a substantially U shaped groove 5, which is adapted toreceive the bead at the opposite side of the tire and it will be readilyseen that when the beads are properly seated within the grooves and theparts of the rim locked together, the tire will be securely fastened inposition around the rim. The ring 4 is held in position on the body 1 bymeans of a locking ring 6, which ring is of less diameter than thediameter of the body and is provided on its outer surface with aplurality of lugs 7, which lugs are adapted to interlock with similarlugs 8 extending inwardly from the inner face of the body 1', said lugsbeing so spaced apart that when the locking ring is turned to a certainposition, the lugs 7 thereon will pass between the lugs 8 and thuspermit the looking ring to be engaged withor removed from the body, andsaid .lugs are also arranged so that when the locking ring is turned toa certain position the lugs 7 will pass to the inside of the lugs 8 andinterlock therewith, thus securely holding the locking ring in position.

At the outer edge of the locking ring 6 is i an upstanding peripheralflange 9,- which flange is of suflicient height to extend a distanceabove the body 1 and when the locking ring is properly positioned withinthe body portion, the flange .9 enters a channel 10 form'ed in the outerface of the ring 4:, said ring 4: when properly positioned on the body,overlapping and protecting the flange 9 from wear, etc.

In order to prevent the locking ring from u rotating when the wheel isin use, the ring a is providedwith atongue 11,Which tongue extends thefull width of the channel 10- and a distance below the inner face of thering fl, the downwardly projecting-portion of the tongue entering a seat12 in the outer face of the body 1, while the body portion ofthe tongueextends through a notch 13 in the flange 9 and it will be readily seenthat when the tongue is seated in the notch 13 and seat 12, the lockingring 6' will befirmly held against rotationindependent of the body 1.

Extending inwardly from the locking ring 61;; a rib 14 upon which blowsareis then introduced over the body portion and moved inwardly until theouter edge thereof is flush with the face of the body,

when the locking ring (3 is entered within the body 1 and said lockingring rotated until the lugs thereon are interlocked with the lugs on thebody}: This operation, when the locking-ring 6 is properly positioned,will bring the notch 13 in registration with the seat 12, whe'nbyinflating the tire the ring l will be moved outwardly until it ongagesthe flange9 and the tongue ll seated in the notch 13-, thusii'i'rerlocking the three parts of the rim and retaining the same inthis position so long as the tire inflated. Should'it be desired toren'iove the tire, the air is removed therefrom, when the ring d ismoved-inwardly until the tongue 11 is free of the notch 13. The lockingring 6 is then rotateduntil the lugs 7 are in registration with thespaces between the lugs when the locking ring may be disengaged from therim proper sothat the ring a may be moved outwardly and the tire leftfree to be moved from off the rim. After a tire has been attached to therimv for some length of time, has a tendency to adhere thereto, thuseausing'a considerable delay in removing the same, but by using myimprovedrimf this objectionable feature overcome, as the tire can bereadily sepa rated from the movable ring and parts of rim, the ringsgagenient with the notch in the locking ring, thus securely interlockingthe parts of the mm;

i The several parts of my improved rim are preferably constructed ofmetal, thereby rendering the same strong and durable and practicallyindestructible from use and by providing the interlocking features asshown, the usual requirement for cotter pins,

screws, wedges and the like is dispensed adaptcd'to.prevent outwardmotion of t first mentioned ring, said flange having notch thereinadapted to receive the tongue of the first mentioned ring, whereby theparts of the rim may be locked together.

2. A rim for vehicle wheels, comprising a body portion having a flangeat one edge thereof, said flange havinga groove, he opposite edge ofsaid body portion. having a seat therein and a plurality-of inwardlyextending lugs, a ring adapted to surround said body, said ring having agroove in one face and a-channel in the opposite face, atongneintersecting said channel and extending belowthe inner edge of. thering,,

said inwardly extending portion engaging the rim when said ring isdisengaged from i of the first mentioned r ng.

the rim. It will further be seen that when a new tire is tobe placedupon the rim, the operation can be quickly accomplished by firstremoving the rings and slipping the tire on the rim, after Which thering l is placed in position around the body of the rim and the lockingring placed inposition. The tire is then inflated, which will move thetongue of the ring on the rim into e.n-

said seat, and a lockingring having a pluralityof lugs thereon adaptedto interlock with the lugs on the body, said locking ring also having aflange adapted to enter the groove in the first mentloned ring, saidhinge having a notch to receive the iflllglle" In testimony whereof Ihave signed my name to this specificatlon-in the presence 0t twosubscribing witnesses.
